All of our canopies will come with a universal electrical apron. Essentially you only need one, but some generators have their electric panel on the short or the long side of their generator, so we offer you a panel to fit either.
It is designed to cover the electronics of the generator while leaving the other three sides open under the tent to ensure proper ventilation. This setup helps prevent overheating and avoids triggering the auto-shutoff on generators with CO sensors.
